Do you know, the air we breathe in our home or at office is hazardous too to our health – and even in many cases, it’s found to be more dangerious than outdoor air even in polluted cities. It happens more often during cold months, when we keep our windows and doors closed most of the times at home, colleges or even at office. We keep ourselves airtight to conserve the heat inside and vice versa for summers too. We (many people) don’t realize that recurring cold people suffer from are majorly caused by the air we breathe from our surrounding where we spend our most time no matter whether it’s home or office.

Effects of Indoor Air Pollution

Effects of Indoor Air Pollution

As per a report from WHO, 63%  of Global Mortality is caused by Non-communicable disease which is linked directly to poor air quality. Long term effects also includes and increase chance of cancer. That’s why people wonder who people get caught of Cancer and everyone remains clueless to it. 2 millions children every year die prematurely every year from Pneumonia. And last not the least, chronic ailments like asthma, allergies and heart and lung diseases symptoms may also appear in healthy persons like you and me.

Sources of Air Pollution

Surprisingly our homes or offices where we spend most of our time are potential source of toxic pollutants like Nitrogen dioxide (NO2), Carbon monoxide, formaldehyde and many more. Here’s a list of pollutants normally found in most household or offices:



Paint & Varnishes: Benzene, Formaldehyde,
Upholstery: TVOCs from Polyurethane
Animal hair & dander
Electronic equipment – TVOCs
Tobacco smoke
Carpet – Toluene, Formaldehyde


Cooking devices – TVOCs from Gasoline, Kerosene
Fuel oil – Benzene, Toluene

Air-conditioning units

Unable to remove PATHOGENS, TVOC & ODOUR
• Circulates without ventilating rooms


• PATHOGENS (From toilet water aerosolisation)

Laundry room

(TVOCs from Methylene Chloride, Toluene,
Heptane, Butane)


(TVOCs from Methylene Chloride, Toluene,
Heptane, Butane)

Most effective Way for Filtering our Indoor Ail Pollution

As per a study by Environmental Protection Agency, an average person spends 80-90% of its life indoor and most of the time is spent at home. Taking the average industrial exposure to 40 hours a week, consider that an infant is exposed to indoor home pollutants for almost 24 hours daily.

And just exchange of air with fresh outdoor air once an hour is not an effective solution for a well-sealed house and it even takes more time for complete air to replace indoor air. And all this ends up building potentially harmful substances in the air.

There are many electrostatic air cleaners available in market which somehow clean the air to some levels, but they also produce Ozone, which is itself a respiratory irritant. Because of such reason, effectiveness of ion exchangers (only plasma filter) as air cleaners are controversial.

Hence, we do need Air Filters which must be capable of removing hazardous gases, bacteria, airborne particles, formaldehyde and above most PM 2.5 particles (PM 2.5 = 2.5 micrometers = 0.0025mm, these particles penetrate into lungs and cause health problems).

Philips is one of such company, whose air filters are capable of purifying air upto 0.02 microns. Their multi-stage filtration system are capable to capture particles captures down to 20 nanometers (0.00002mm)2 and are 100% Ozone free.

Philips Air Purifier AC4072

Their Multi-Stage purification process includes following filters:

Pre-Filter – Traps larger particles, pet hairs, dust and dust mites

Activated Carbon Filter – Odours from Cooking, Tobacco smoke & TVOCs (Benzene, Formaldehyde)

HEPA Filter – Tobacco smoke, Mold, Car exhaust, Bacteria and Viruses

Hence, like many thinks that even air conditioners are enough to purify air is just not reasonable nor exchanging air from outside from time to time. We need a system which could purify the air constantly during whole period we spend indoors, no matter whether it’s at office or home.
